REFRIGERATINC E APPLIANCE Filed May 2, 1929' 2 Sheets-Sheet 2 gnoc'nfoi Charles A. Mom Q Patented Jan. 20, 19315 7 UNITED STATES CHARLES A. moons, or mama, mmmiso'm My invention relates to improvements in refrigerating appliances.

Objects of the invention are to provide a simple refrigerating unit for overhead mstallation in a room; to provide in such unit an elongated cooling duct structure through which gravitating air is conducted and which is disposed so as to set up a definite circulation of air within the room; to provide means 10 for stimulating such circulation, and to provide means for introducing fresh air into the room; Another object is to provide an appliance for cooling the air in a room and causing the same to clrculate therein, by gravity, in a definite manner, whereby the air is drawn into the appliance at the ceiling from end to end of the room and imparted downward in refrigerated condition centrally of the room.

With the foregoing and other objects in View, which will appear in .the following description, the invention resides in the novel combination and arrangement of parts and in details of construction hereinafter described and claimed.

In the drawings, Fig. 1 is a view illustrating a room structure fragmentarily and in section, the same also showing in longitudinal central section a form of appliance embodying my invention; Fig. 2 is a detail sectional View taken transversely of the appliance as "on the line 22 of Fig. 1 and Fig.3 is a bottom view of said appliance.

Referring to the drawing, wherein like reference characters are employed to designate similar parts throughout the several views, a room A is provided within the illustrated building structure, which includes end walls 10, side walls 11 and ceiling 12.

The appliance shown is an elongated structure arranged longitudinally of the room, near the ceiling 12, centrally thereof. It consists mainly of reaches of a pipe X disposed closely one with respect to another and arranged to provide upper and lower ducts or channels B and C, the structure including side wall reaches 13, top and bottom wall reaches 14, 15 and partition wall reaches 16, an inlet opening (1 being provided between reaches 14 in the upper wall, openings e being pro- PATENT OFF-ICE zan rnrennarme AI'PLIANCE a Application filed Kay 2, 1929.

vided in the partitioning wall by fore-shortening the reaches 16 and a central opening being provided in the bottom wall by approp riately arrangingthe reaches 15 as shown in ant at one end from any suitable feed main and returns it from the otherend thereof to any suitable return main. The reaches of said pipe are arranged in such near proximity to each other as to be frostedtogether except at the openings 0!, e and f. The said longitudinally-extending reaches of pipe. are 1 confined to thebody of the appliance for the sake of simplicity of construction, end panels 17 being provided to close the extremities of the ducts B, C. These panels are supported from the ceiling 12 by hanger straps 18, the reachesof pipe being likewise supported by hanger straps .19, 20, the latter being U-shaped, as shown.

A conduit 21, fitted with a damper 22 and cured. A fan 26 mounted on the shaft of this motor is disposed in the opening f. v

Tn operation, the air at the ceiling 12 of the room in proximity to the elongated opening d enters the upper duct B through said opening and flows alongsaid duct to the nearest opening e between the upper duct B and the lower duct C. Passing through these openings, the air moves along the lower duct 0 from the ends thereof to the central opening f through which it descends centrally of the room. Spreading out in all directions toward the relatively warm walls, the air ascends to the upper portion of the room, returning along the ceiling thereof to position over the opening d, thus completing a gravitating cycle of movement. This movement of the air may be stimulated by putting the 55 The continuous pipeX receives arefrigerfan motor 7 into operation and regulated quantities of fresh air may be admitted to the room by opening the dam er 22 more or less in conduit 21, natural lea a e from the 5 room or the egress of air there rom, as by means of any suitable construction, providingfor the escape of air from the room.

Changes in the specific form of my invention, as herein disclosed, may be made within the scope of what is claimed without departin from the spirit of my invention.

aving described my invention, What I claim as new and desire to protect byLetters Patent is: r

1. In combination, a room, a refrigerating appliance therein comprising a double duct structure disposed longitudinally of the room near the ceiling centrally thereof and providing two cooling channels, a first channel with an upper inlet opening extending therealong and a second channel with a lower central outlet opening, said channels being in communication with each other at their correwith a central outlet opening in the bottom thereof, said channels being in communication with each other at their corresponding ends, and a fan disposed adjacent said central opening for impelling the flow of air throu h the duct structure.

3. n combination, a room, a refrigerating appliance therein comprising a double duct structure disposed longitudinally of the room near the ceiling centrally thereof and providing two cooling channels, a first channel with an upper inlet opening extending therealong and a second channel with a lower central outlet opening, said channels being in communication with each other at their corresponding ends, and a fan disposed adjacent said centralopeningior impelling the'flow of air through the duct structure.

4. In combination, a room,a refrigeratmg appliance therein comprising a double duct along the top thereof and a second channel.

5. Incombination, a room, a refrigerating appliance therein comprising a double duct structure disposed near the ceiling of the room and providing a first coolin channel and a second cooling channel, the rst channel having an inlet opening extending therealong and the second channel having a cennel having an inlet opening extending therealong and the second channel having a central outlet opening, said outlet opening being at a lower elevation than said inlet opening, said channels being in communication with each other at their corresponding ends.

In testimony whereof I have aflixed my signature to this s ecification.
